TURBINE.

Specification of Letters Patent. Application filed December 27, 19 11.

Patented Mar. 17, 1914. Serial No. 668,033.

To all whom it may concern Be it known that I, OT'ro BANNER, a subject of the German Emperor, and resident of Easton, in the county of Northampton and State of Pennsylvania, have invented a new and useful Improvement in Turbine- Engines, of which the following is a specification.

This invention consists of a horizontal double flow turbine engine of the so-called action or velocity type and is particularly applicable to those cases where it is desirable to drive one set. of blades while another set may be running idly up to a certain load when the fluid may be turned onto said idly running set.

This invention is especially well adapted for use in connection with low pressure work but is not limited to such use.

A practical embodiment of my invention is represented in the accompanying drawing which is a View of the engine half in side elevation and half in longitudinal central vertical section.

The engine shaft is denoted by l, the blade wheels fixed thereon by 2 and their 3. The casing is provided at its ends with chambers 4, 5, communicating with their inlets 6, 7. ther provided wit-h an intermediate outlet chamber 8 communicating with the outlet 9.

The transverse partitions alternating with the blade wheels and carried by the casing are denoted by 10 and are provided with nozzles 11.

The bearings for the shaft 1 at the opposite ends of the casing are preferably divided in a horizontal plane coincident with the axis of the shaft to form upper and lower members 12, 13, and 14:, 15, respectively. The casing is preferably divided in a horizontal plane co-incident with the axis of the shaft and also in transverse vertical planes to form upper and lower end members 16, 17 and 18, 19; upper and lower cylinder members 20, 21, and 22, 23; and upper and lower divided ring members 24, 25, and 26, 27 the lower half cylinder members 21, 23, being provided with brackets 28,

The casing is fur-' 29, for supporting the engine. Valves 30, 31, are provided for independently controlling the admission of the motive fluid to the inlet chambers 4, 5.

In the accompanying drawings, the turbine is shown as having four stages upon each side of the intermediate exhaust chamher and the wheels are shown as having single rows of blades but the number of stages and the number of rows of blades may be varied as desired.

In an engine constructed as here-in shown and described, the motive fluid may be fed to one set of wheels while the other set of Wheels runs idly and when the work has reached a certain point then the motive fluid may be fed to the other set of wheels for driving them.

What I claim is 1. A turbine engine comprising a casing divided in transverse vertical planes to form two end members having inlet chambers therein, an intermediate ring member having an outlet chamber therein and cylinder members located between the ring member and end members.

2. A turbine engine comprising a casing including two end members having inlet chambers and an intermediate ring member having an outlet chamber, said end members and intermediate ring member being divided longitudinally into half sections.

3. A turbine engine comprising a casing including two end members having inlet chambers and an intermediate divided ring member having an outlet chamber, said end members and intermediate ring member be ing divided longitudinally into half sections.

4. A turbine engine comprising a casing divided in horizontal and transverse vertical planes to form upper and lower end members, upper and lower cylinder members and upper and lower intermediate ring members, the end members containing the inlet chambers, and the intermediate ring member the outlet chamber.

5. A turbine engine comprising a casing divided in horizontal and transverse vertical planes to form upper and lower end as my invention, I have signed my name in members, upper and lower cylinder mempresence of tWo witnesses, this 23d day of hers and intermediate divided upper and Dec. 1911.
